The microwave motion sensor is a microwave moving object detector which is designed according to the principle of Doppler Radar. It is widely used not only in the detection of human body, but also many other objects. With the character of long detection distance and high sensitivity, it works without the limitation of ambient temperature and has come widely used in industrial, transportation and civil applications such as measuring vehicle speed, liquid levels, automatic door motion detection, automatic washing, production line material detection and car reversing sensors etc.
